request.getParameter(“xxx”)的参数的取值

request.getParameter(“xxx”)的参数的取值的几种可能:

1. Html中form表单中标签的name属性:

<form name="form" method="post" action="checkUser">

请输入用户姓名:<input type="text" name="username">

<input type="submit" name="Submit" value="提交">

</form>

request.getParameter(“username”);

2. Html中form表单提交时的action的参数

<form name="form" method="post" action="checkUser?Flag=1&Id=2">

请输入用户姓名:<input type="text" name="username">

<input type="submit" name="Submit" value="提交">

</form>

request.getParameter(“username”);

request.getParameter(“Flag”);

request.getParameter(“Id”);

3. Html中url的内容

<a href="SortServlet?flag=5&temp=2" onclick="sort()"><img src="data:images/cbsj.jpg" /></a>

request.getParameter(“flag”);

request.getParameter(“temp”);

4. Ajax中的data

<form name="fm" action="" method="post">

<div style="margin-bottom:10px;">

<input class="TxtUserNameCssClass" type="text" id="UserCode" value="" />

</div>

<div style="margin-top:20px;">

<input class="TxtPasswordCssClass" type="Password" id="UserPwd" value="" />

</div>

</form>

<div class="IbtnEnterCssClass" id="IbtnEnter" onclick="submitForm()">登录</div>

function submitForm(){

var UserCode = $("#UserCode").val();

var UserPwd = $("#UserPwd").val();

var mypwd = $.base64.btoa($.md5(UserPwd).toUpperCase());

var checkUserParams = {

usercode:UserCode,

userpwd:mypwd

};

$.ajax({

url : 'checkUser.asp?mathid='+Math.random(),

type : 'post',

data : checkUserParams,

dataType:'json',//接受数据格式

success : function(data) {

},

failure : function(data) {

}

});

}

request.getParameter("usercode");

request.getParameter("userpwd");
